Модуль сканера A-B 1747-SDN SLC 500 DeviceNet

Description

The Allen-Bradley 1747-SDN is an SLC 500 DeviceNet scanner module.

The module communicates with DeviceNet adapter modules connected to a DeviceNet network.

It is compatible with SLC 5/02 or later controllers. It is a single-slot module that supports operation in slave mode and passes messages in polled, pass-through, state change, cyclic I/O, and pass-through configurations.

It has a backplane current consumption of 5V DC, 500 mA.

About the 1747-SDN

The Allen-Bradley 1747-SDN is a DeviceNet communications scanner.

This scanner module is used to communicate with DeviceNet-enabled devices over a DeviceNet network or through a DeviceNet adapter module.

The module can operate in slave mode; send and receive messages in polled, select-through, state change, and cyclic I/O configurations.

It also supports a pass-through configuration where the 1747-SDN acts as a bridge and connects to a separate DeviceNet network.

This pass-through feature is intended to replace the 1770-KFD, 1784-PCD, 1784-PCID, or 1784-PCIDS DeviceNet connections on the network.

Specifically, the compatible SLC 500 processors when implementing the pass-through configuration are the SLC 5/03. SLC 5/04. and SLC 5/05.

The 1747-SDN supports configuration of up to 63 nodes at a baud rate of 125 Kbps. It draws 5V DC, 500 mA of backplane current.

The 1747-SDN has two (2) LED status indicators mounted on the front panel, such as the Module Indicator to report module operation and a Network Status LED to indicate the DeviceNet communication link.

It also has an LCD display that provides module address and error indications.The DeviceNet terminal is mounted behind the access door and is equipped with a 10-pin plug that plugs into the DeviceNet port.

It serves as an interface between the SLC processor and DeviceNet devices, allowing communication with the processor via M1/M0 file transfer and discrete I/O. The 1747-SDN is compatible with the SLC processor.
